Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused inputs?

Unused inputs must be terminated at VCC or GND to prevent excessive power consumption and potential oscillations.

What is the function of the OE pins?

The Output Enable (OE) pins control the state of the outputs. When low, the outputs are enabled; when high, they enter a high-impedance state.
